Herg potassium current
hERG (the human Ether-à-go-go-Related Gene) is a gene (KCNH2) that codes for a protein known as Kv11.1, the alpha subunit of a potassium ion channel. This ion channel (sometimes simply denoted as 'hERG') is best known for its contribution to the electrical activity of the heart: the hERG channel … Zobacz więcej hERG forms the major portion of one of the ion channel proteins (the 'rapid' delayed rectifier current (IKr)) that conducts potassium (K ) ions out of the muscle cells of the heart (cardiac myocytes), … Zobacz więcej A detailed atomic structure for hERG based on X-ray crystallography is not yet available, but structures have recently been solved by electron microscopy. In the laboratory the Zobacz więcej This channel is also sensitive to drug binding, as well as decreased extracellular potassium levels, both of which can result in decreased … Zobacz więcej The hERG gene was first named and described in a paper by Jeff Warmke and Barry Ganetzky, then both at the University of Wisconsin–Madison. The hERG gene is the human homolog of the Ether-à-go-go gene found in the Drosophila fly; Ether-à-go-go was … Zobacz więcej Loss-of-function mutations in this channel may lead to long QT syndrome (LQT2), while gain-of-function mutations may lead to short QT syndrome. Both clinical disorders stem … Zobacz więcej Due to the documented potential of QT-interval-prolonging drugs, the United States Food and Drug Administration issued recommendations for the establishment … Zobacz więcej HERG has been shown to interact with the 14-3-3 epsilon protein, encoded by YWHAE. Zobacz więcej WitrynaMutations in the human ether-a-go-go-related gene (hERG) cause long-QT syndrome type 2 (LQT2). We previously described a homozygous LQT2 nonsense mutation Q1070X in which the mutant mRNA is degraded by nonsense-mediated mRNA decay (NMD) leading to a severe clinical phenotype.
